A 0.240-kg billiard ball that is moving at 3.00 m/s strikes
the bumper of a pool table and bounces straight back at
2.40 m/s (80% of its original speed). The collision lasts
0.0150 s. (a) Calculate the average force exerted on the
ball by the bumper. (b) How much kinetic energy in
joules is lost during the collision? (c) What percent of the
original energy is left?

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
